Like so many of his fellow Saturday Night Live (SNL) alumni, Bill Murray honed his improvisational comedic skills as part of Chicago's Second City. After Chevy Chase left SNL for a Hollywood film career, Murray replaced him, appearing from 1977 to 1980, and developing some of the most memorable but nameless characters on the show, such as his sleazy lounge lizard singer and Todd the geek. Murray has appeared in a long list of successful comedies, including Meatballs (1979), Caddyshack (1980), Stripes (1981), Ghostbusters (1984), What About Bob? (1991), Groundhog Day (1993), and the Michael Jordan animated vehicle Space Jam (1996). He plays Polonius in Michael Almereyda's Hamlet (2000) and John Bosley in the movie version of Charlie's Angles (2000).
